下面结合附图，通过具体的实施例及其应用场景对本申请实施例提供的图像拍摄方法进行详细地说明。The image capturing method provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.
请参见图1，图1是本申请实施例提供的一种图像拍摄方法的流程图，该方法应用于电子设备。该电子设备可以包括第一摄像头、第二摄像头、自 由云台和固定云台。其中，第一摄像头安装在自由云台上，第二摄像头安装在固定云台上。自由云台和固定云台都是安装、固定摄像头的支撑设备，可以起到防抖动的效果，无需额外的固定设备。Please refer to FIG. 1. FIG. 1 is a flowchart of an image capturing method provided by an embodiment of the present application, and the method is applied to an electronic device. The electronic device may include a first camera, a second camera, a free pan/tilt and a fixed pan/tilt. Among them, the first camera is installed on the free pan-tilt, and the second camera is mounted on the fixed pan-tilt. Both the free gimbal and the fixed gimbal are support devices for installing and fixing the camera, which can achieve the effect of anti-shake without additional fixed equipment.
如图1所示，本申请实施例中的图像拍摄方法可以包括如下步骤：As shown in FIG. 1 , the image capturing method in this embodiment of the present application may include the following steps:
步骤101：接收用于触发图像拍摄的第一输入。Step 101: Receive a first input for triggering image capture.
本实施例中，当启动电子设备中的拍摄功能之后，可以通过用户点击拍摄按钮向电子设备输入用于触发图像拍摄的指令。相应的，电子设备接收用于触发图像拍摄的第一输入。In this embodiment, after the shooting function in the electronic device is activated, an instruction for triggering image shooting may be input to the electronic device by the user clicking the shooting button. Correspondingly, the electronic device receives a first input for triggering image capturing.
步骤102：响应于第一输入，获取第一摄像头拍摄的多帧第一图像，和获取第二摄像头拍摄的多帧第二图像。Step 102: In response to the first input, acquire multiple frames of first images captured by the first camera, and acquire multiple frames of second images captured by the second camera.
本实施例中，在图像拍摄过程中，自由云台控制第一摄像头的实际拍摄位置不变，固定云台控制第二摄像头随着电子设备同步移动/运动。也就是说，自由云台的作用是在电子设备进行正方向旋转时，控制其上的第一摄像头进行反方向的旋转，或者在电子设备进行反方向旋转时，控制其上的第一摄像头进行正方向的旋转，从而锁定拍摄对象，保证第一摄像头的实际拍摄位置不变。固定云台的作用是在图像拍摄过程中控制第二摄像头随着电子设备同步移动，即控制第二摄像头与电子设备保持相对静止，当电子设备转动时，提供适当的防抖效果，保证图像的质量。In this embodiment, during the image capturing process, the actual shooting position of the first camera controlled by the free pan/tilt remains unchanged, and the fixed pan/tilt controls the second camera to move/move synchronously with the electronic device. That is to say, the function of the free gimbal is to control the first camera on the electronic device to rotate in the reverse direction when the electronic device rotates in the forward direction, or control the first camera on it to rotate when the electronic device rotates in the reverse direction. The rotation in the positive direction locks the shooting object and ensures that the actual shooting position of the first camera remains unchanged. The function of the fixed pan/tilt is to control the second camera to move synchronously with the electronic device during the image capture process, that is, to control the second camera and the electronic device to remain relatively still, and to provide an appropriate anti-shake effect when the electronic device rotates to ensure the image quality. quality.
一具体示例中，对于第一摄像头拍摄的第一图像和/或第二摄像头拍摄的第二图像，可以以缓冲队列的形式在电子设备中存储，当存储图像达到上限后，可以丢弃缓冲队列的队头的存储图像，并在缓冲队列的队尾继续存储新的拍摄图像。该上限可以基于用户实际情况设定。比如该上限可以设定为2s内拍摄的图像数量，即若第一摄像头和第二摄像头每秒拍摄30帧图像，则缓冲队列的上限为60帧图像。In a specific example, the first image captured by the first camera and/or the second image captured by the second camera may be stored in the electronic device in the form of a buffer queue. When the stored images reach the upper limit, the buffer queue may be discarded. Store images at the head of the queue, and continue to store new captured images at the tail of the buffer queue. The upper limit can be set based on the actual situation of the user. For example, the upper limit may be set to the number of images captured within 2s, that is, if the first camera and the second camera capture 30 frames of images per second, the upper limit of the buffer queue is 60 frames of images.
步骤103：对多帧第一图像和多帧第二图像进行合成，得到合成图像。Step 103: Synthesize multiple frames of the first image and multiple frames of the second image to obtain a combined image.
需指出的，本申请实施例不限定图像合成方式，可以采用现有的图像合成方式。本申请实施例适用的场景包括但不限于多帧图像拍摄场景，比如流光快门的拍摄场景、全景拍摄场景等。It should be noted that the embodiments of the present application do not limit the image synthesis method, and an existing image synthesis method may be used. Scenarios applicable to the embodiments of the present application include, but are not limited to, multi-frame image shooting scenarios, such as streaming shutter shooting scenarios, panoramic shooting scenarios, and the like.
本申请实施例的图像拍摄方法，在接收用于触发图像拍摄的第一输入之 后，可以获取安装在自由云台上的第一摄像头拍摄的多帧第一图像，和获取安装在固定云台上的第二摄像头拍摄的多帧第二图像，并对多帧第一图像和多帧第二图像进行合成，得到合成图像。这样，通过云台代替三脚架等器材来辅助多帧图像的拍摄，可以降低拍摄难度。进一步的，由于在图像拍摄过程中，自由云台控制第一摄像头的实际拍摄位置不变，固定云台控制第二摄像头随着电子设备同步移动，因此可以使得第一摄像头和第二摄像头拍摄到不同的图像内容，从而使得最后合成的图像包含较多的图像内容，提升图像质量。In the image capturing method of the embodiment of the present application, after receiving the first input for triggering image capturing, multiple frames of first images captured by the first camera installed on the free gimbal may be obtained, and multiple frames of the first image captured by the first camera installed on the free gimbal may be obtained, and multiple frames of the first image captured by the first camera installed on the free gimbal may be obtained, and the first image captured by the first camera installed on the free gimbal may be obtained The multi-frame second image captured by the second camera is synthesized, and the multi-frame first image and the multi-frame second image are synthesized to obtain a composite image. In this way, the shooting difficulty can be reduced by using a gimbal instead of a tripod and other equipment to assist the shooting of multi-frame images. Further, during the image capturing process, the actual shooting position of the first camera controlled by the free pan-tilt remains unchanged, and the fixed pan-tilt controls the second camera to move synchronously with the electronic device, so the first camera and the second camera can capture the image. Different image contents, so that the final synthesized image contains more image contents and improves the image quality.
本申请实施例中，为了保证图像合成效果，可以从多帧第一图像中选择第一目标图像，和从多帧第二图像中选择第二目标图像，并对第一目标图像和第二目标图像进行合成，得到合成图像。其中，第一目标图像的数量可以为一帧或者多帧。第二目标图像的数量可以为一帧或者多帧。在选择第一目标图像和第二目标图像时，电子设备可以基于用户选择操作来选择，也可以基于电子设备中预设的选择规则来选择，对此不进行限制。In this embodiment of the present application, in order to ensure the image synthesis effect, a first target image may be selected from multiple frames of first images, and a second target image may be selected from multiple frames of second images, and the first target image and the second target image may be selected. The images are composited to obtain a composite image. The number of the first target images may be one frame or multiple frames. The number of the second target images may be one frame or multiple frames. When selecting the first target image and the second target image, the electronic device may select based on a user selection operation, or may select based on a preset selection rule in the electronic device, which is not limited.
可选的，上述步骤103中的图像合成过程可以包括：从多帧第一图像中选择第一目标图像，和从多帧第二图像中选择多帧第二目标图像；利用多帧第二目标图像对第一目标图像进行图像内容补充，得到合成图像。Optionally, the image synthesis process in the above step 103 may include: selecting a first target image from multiple frames of first images, and selecting multiple frames of second target images from multiple frames of second images; using multiple frames of second target images; The image supplements the image content of the first target image to obtain a composite image.
一种实施方式中，第一目标图像和第二目标图像可以是在拍摄完成之后从缓存图像中选择的。这样，在拍摄完成后再选择第一目标图像和第二目标图像，可以实现从全量缓存图像中进行选择，从而保证所选图像的质量。In one embodiment, the first target image and the second target image may be selected from cached images after the shooting is completed. In this way, after the shooting is completed, the first target image and the second target image can be selected, which can realize selection from the full amount of cached images, thereby ensuring the quality of the selected images.
需指出的，由于第一摄像头的实际拍摄位置不变，即第一摄像头实际上是在起始拍摄位置拍摄的多帧图像，因此在从第一摄像头拍摄的多帧第一图像中选择第一目标图像时，可以将第一目标图像选为多帧第一图像中的清晰度最高的图像。由于第二摄像头在图像拍摄过程中进行了移动或旋转，即第二摄像头拍摄的图像是不同场景下的图像，因此为了保证图像合成效果，可以从第二摄像头拍摄的第二图像中选择多帧第二目标图像，且多帧第二目标图像分别为第二摄像头在旋转至不同角度时拍摄的图像。比如，若自由云台的最大旋转角度为T，选择6帧第二目标图像，则这6帧第二目标图像可以为分别对应于自由云台旋转角度为T/6、T/3、T/2、2T/3、5T/6、T时的图像。It should be pointed out that since the actual shooting position of the first camera does not change, that is, the first camera is actually a multi-frame image shot at the starting shooting position, the first When the target image is selected, the first target image may be selected as the image with the highest definition among the multiple frames of the first image. Since the second camera moves or rotates during the image capturing process, that is, the images captured by the second camera are images in different scenes, so in order to ensure the image synthesis effect, multiple frames can be selected from the second images captured by the second camera The second target image, and the multiple frames of the second target image are respectively images captured by the second camera when rotated to different angles. For example, if the maximum rotation angle of the free pan/tilt head is T, and 6 frames of second target images are selected, the 6 frames of second target images may be corresponding to the free pan/tilt head rotation angles of T/6, T/3, T/ 2, 2T/3, 5T/6, T images.
这样，可以使得合成图像既包含了起始拍摄位置时的图像内容，又补充了电子设备旋转后的图像内容，从而保证了合成图像的质量。In this way, the composite image can not only include the image content at the initial shooting position, but also supplement the image content after the electronic device is rotated, thereby ensuring the quality of the composite image.
本申请实施例中，由于自由云台的旋转角度超过预设阈值时，无法锁定第一摄像头的起始拍摄位置不变，即当自由云台的旋转角度达到预设阈值时，就达到了其锁定第一摄像头的极限，如果继续旋转则无法锁定第一摄像头的起始拍摄位置不变，因此，当电子设备监测到自由云台的旋转角度达到预设阈值时，可以停止拍摄过程。该预设阈值可以基于相应自由云台设置。In the embodiment of the present application, when the rotation angle of the free pan/tilt exceeds the preset threshold, the initial shooting position of the first camera cannot be locked, that is, when the rotation angle of the free pan/tilt reaches the preset threshold, the The limit of the first camera is locked. If it continues to rotate, the initial shooting position of the first camera cannot be locked. Therefore, when the electronic device detects that the rotation angle of the free gimbal reaches a preset threshold, the shooting process can be stopped. The preset threshold can be set based on the corresponding free PTZ.
可选的，本实施例的图像拍摄方法还可以包括：在监测到自由云台的旋转角度达到预设阈值，或者接收到用于触发停止图像拍摄的输入的情况下，停止拍摄过程。Optionally, the image capturing method of this embodiment may further include: stopping the capturing process when it is monitored that the rotation angle of the free pan/tilt head reaches a preset threshold, or an input for triggering stop of image capturing is received.
也就是说，在图像拍摄过程中，电子设备可以监测自由云台的旋转角度是否达到预设阈值，或者是否接收到用于触发停止图像拍摄的输入，并在监测到自由云台的旋转角度达到预设阈值，或者接收到用于触发停止图像拍摄的输入的情况下，停止拍摄过程。该输入可以是通过用户点击拍摄按钮实现的。That is to say, during the image capture process, the electronic device can monitor whether the rotation angle of the free gimbal reaches a preset threshold, or whether it receives an input for triggering the stop of image capture, and monitors that the rotation angle of the free gimbal reaches a predetermined threshold. A preset threshold, or if an input is received to trigger the stop of image capture, the capture process is stopped. The input may be achieved by the user clicking the capture button.
本申请实施例中，第一目标图像和第二目标图像可以是基于用户选择操作选择的。上述选择第一目标图像和第二目标图像的过程可以包括：In this embodiment of the present application, the first target image and the second target image may be selected based on a user selection operation. The above process of selecting the first target image and the second target image may include:
接收对多帧第一图像和多帧第二图像的第二输入；该第二输入可以包括但不限于按压操作、滑动操作等；Receive a second input for multiple frames of first images and multiple frames of second images; the second input may include but is not limited to pressing operations, sliding operations, etc.;
响应于第二输入，从多帧第一图像中选择第一目标图像，和从多帧第二图像中选择多帧第二目标图像。In response to the second input, the first target image is selected from the plurality of frames of the first images, and the plurality of frames of the second target image is selected from the plurality of frames of the second image.
这样，借助用户选择操作来选择所需的第一目标图像和第二目标图像，可以保证所选图像的质量，进而提升后续图像合成效果。In this way, by using the user selection operation to select the required first target image and the second target image, the quality of the selected image can be guaranteed, thereby improving the effect of subsequent image synthesis.
一具体示例中，在图像拍摄完成之后，可以在电子设备的显示界面上显示出已缓存的多帧第一图像和多帧第二图像，以供用户从多帧第一图像中选择第一目标图像，和从多帧第二图像中选择第二目标图像。该多帧第一图像和多帧第二图像在电子设备的显示界面上可以同时显示，也可以依次显示出，比如先显示多帧第一图像再显示多帧第二图像，或者先显示多帧第二图像再显示多帧第一图像。In a specific example, after the image capturing is completed, the buffered multi-frame first images and multi-frame second images may be displayed on the display interface of the electronic device, so that the user can select the first target from the multi-frame first images image, and selecting a second target image from the plurality of frames of the second image. The multiple frames of the first image and the multiple frames of the second image may be displayed simultaneously on the display interface of the electronic device, or may be displayed sequentially, for example, the multiple frames of the first image are displayed first and then the multiple frames of the second image are displayed, or the multiple frames are displayed first. The second image then displays multiple frames of the first image.
可选的，本实施例的图像拍摄方法还可以包括：在预览界面上展示第二摄像头拍摄的图像，以供用户查看。Optionally, the image capturing method in this embodiment may further include: displaying the image captured by the second camera on the preview interface for the user to view.
需指出的，由于第一摄像头的实际拍摄位置不变，即锁定了起始拍摄位置的图像，而第二摄像头拍摄的图像是不同场景下的图像，因此不需要在预览界面展示第一摄像头拍摄的图像，只展示第二摄像头拍摄的图像即可。It should be pointed out that since the actual shooting position of the first camera does not change, that is, the image of the starting shooting position is locked, and the image captured by the second camera is an image in a different scene, so there is no need to display the shooting of the first camera on the preview interface. , only display the image captured by the second camera.
下面结合图2至图5对本申请具体实例进行详细说明。Specific examples of the present application will be described in detail below with reference to FIGS. 2 to 5 .
本申请具体实例中，以电子设备为手机为例，手机包括第一后置摄像头、第二后置摄像头、自由云台和固定云台，其中，第一后置摄像头安装在自由云台上，第二后置摄像头安装在固定云台上。如图2所示，以流光快门拍摄为例的图像拍摄过程可以包括如下步骤：In the specific example of this application, taking the electronic device as a mobile phone as an example, the mobile phone includes a first rear camera, a second rear camera, a free gimbal and a fixed gimbal, wherein the first rear camera is installed on the free gimbal, The second rear camera is mounted on a fixed gimbal. As shown in FIG. 2 , the image capturing process using streamer shutter shooting as an example may include the following steps:
步骤201：手机基于用户输入，开启相机应用，打开第一后置摄像头和第二后置摄像头，并进入双云台拍摄模式。Step 201: Based on the user input, the mobile phone starts the camera application, turns on the first rear camera and the second rear camera, and enters the dual-camera shooting mode.
如图3所示，在手机开启相机应用，打开后置摄像头之后，手机界面上可显示出供用户选择的是否进入双云台拍摄模式的信息。在用户点击“专业”按钮之后，即可进入双云台拍摄模式。As shown in FIG. 3 , after the camera application is opened on the mobile phone and the rear camera is turned on, the interface of the mobile phone can display information for the user to choose whether to enter the dual-header shooting mode. After the user clicks the "Pro" button, they can enter the dual-head shooting mode.
步骤202：手机基于用户点击拍摄按钮的操作，接收用于触发图像拍摄的输入，并开始进行图像拍摄。Step 202: The mobile phone receives an input for triggering image shooting based on the user's operation of clicking the shooting button, and starts image shooting.
由于双云台拍摄模式下，自由云台和固定云台同时生效，自由云台会将当前拍摄的图像锁定，当手机在一定范围移动时，自由云台也会进行对应的移动，保证拍摄的实际位置相同。因此当用户开始进行流光快门的拍摄时，需要按下拍摄按钮，按下后立即开始图像拍摄。Since in the dual-gimbal shooting mode, the free gimbal and the fixed gimbal take effect at the same time, and the free gimbal will lock the currently captured image. The actual location is the same. Therefore, when the user starts to shoot the streamer shutter, the user needs to press the shooting button, and the image shooting starts immediately after pressing the button.
步骤203：在图像拍摄过程中，手机移动，自由云台控制第一后置摄像头的实际拍摄位置不变，即锁定起始拍摄位置，并缓存第一后置摄像头拍摄的第一图像。Step 203: During the image shooting process, the mobile phone moves, and the actual shooting position of the first rear camera controlled by the free gimbal remains unchanged, that is, the initial shooting position is locked, and the first image captured by the first rear camera is cached.
步骤204：在图像拍摄过程中，手机移动，固定云台控制第二后置摄像头随着手机同步移动，即手机与第二后置摄像头保持相对静止，并缓存第二后置摄像头拍摄的第二图像。Step 204: During the image capturing process, the mobile phone moves, and the fixed PTZ controls the second rear camera to move synchronously with the mobile phone, that is, the mobile phone and the second rear camera remain relatively stationary, and the second rear camera captured by the second rear camera is cached. image.
其中，在拍摄流光快门的过程中，经常需要长时间的曝光，在这个过程中，固定云台就能提供适当的防抖效果，不需要额外使用固定设备。Among them, in the process of shooting the streamer shutter, a long exposure is often required. In this process, a fixed gimbal can provide a proper anti-shake effect, and no additional fixed equipment is required.
步骤205：判断自由云台的旋转角度是否达到预设阈值，或者是否接收到用于触发停止图像拍摄的输入。Step 205: Determine whether the rotation angle of the free pan/tilt head reaches a preset threshold, or whether an input for triggering stop of image capturing is received.
一种实施方式中，由于自由云台并不能无休止地抵消摄像头的位移，因此在手机移动过程中，可以通过如图4所示的手机界面上的矩形框来展现自由云台的转动情况，以便用户了解自由云台移动情况。In one embodiment, since the free gimbal cannot endlessly offset the displacement of the camera, during the movement of the mobile phone, the rotation of the free gimbal can be displayed through the rectangular frame on the mobile phone interface as shown in FIG. 4 . In order for users to understand the movement of the free PTZ.
在拍摄流光快门的光绘场景时，自由云台已经锁定了起始拍摄位置，随着用户开始绘制光绘的图案，拍摄用户开始把手机进行对应的移动，直到完成整个图案的绘制。在拍摄过程中，手机应用需要判断是否达到了自由云台旋转的最大值。假设自由云台最大的旋转角度为T，当手机开始移动时，自由云台会通过自身的转动，锁定起始拍摄位置，当自由云台旋转的角度达到T时，说明达到了拍摄的极限，如果继续旋转，则自由云台无法再锁定拍摄的起始位置了。当用户再次按下拍摄按钮即输入拍摄停止指令，或者旋转达到自由云台的极限时，拍摄完成，进入步骤206。When shooting the light painting scene of the streamer shutter, the free gimbal has locked the starting shooting position. As the user starts to draw the light painting pattern, the shooting user starts to move the mobile phone correspondingly until the entire pattern is drawn. During the shooting process, the mobile phone application needs to determine whether the maximum free gimbal rotation has been reached. Assuming that the maximum rotation angle of the free gimbal is T, when the mobile phone starts to move, the free gimbal will lock the starting shooting position through its own rotation. When the rotation angle of the free gimbal reaches T, it means that the shooting limit has been reached. If you continue to rotate, the free head can no longer lock to the starting position of the shot. When the user presses the shooting button again to input a shooting stop instruction, or when the rotation reaches the limit of the free pan/tilt head, the shooting is completed, and the process proceeds to step 206 .
步骤206：拍摄完成之后，读出第一后置摄像头拍摄的第一图像，并从中选取第一目标图像，和读出第二后置摄像头拍摄的第二图像，并从中选取多帧第二目标图像。Step 206: After the shooting is completed, read out the first image captured by the first rear camera, and select the first target image from it, and read out the second image captured by the second rear camera, and select multiple frames of the second target from there image.
由于自由云台一直锁定着拍摄的起始位置，拍摄的图像更为重要，而固定云台随着手机转动拍摄，补充了更多的细节。因此，在读出这两个云台对应的图像时，自由云台对应的图像选最清晰的即可，而固定云台对应的图像是不同场景下的图像，需要选取不同旋转角度下的多帧图像。Since the free gimbal is always locked to the starting position of the shooting, the captured image is more important, while the fixed gimbal rotates with the phone to shoot, adding more details. Therefore, when reading out the images corresponding to the two PTZs, the image corresponding to the free PTZ can be selected the clearest, while the images corresponding to the fixed PTZ are images in different scenarios, and it is necessary to select the images corresponding to different rotation angles. frame image.
步骤207：对第一目标图像和多帧第二目标图像进行合成，得到合成图像。Step 207: Synthesize the first target image and multiple frames of the second target image to obtain a combined image.
比如，如图5所示，左一为自由云台拍摄的第一图像，由于拍摄了多帧，可以通过点击该区域，弹出保存的一系列比较清晰的图像，并基于用户输入选取最清晰的图像。左二和左三是通过固定云台与手机旋转得到的扩展的图像，可以由用户自由选择，补充起始拍摄场景之外的更多的场景。用户选择了需要合成的图像后，由后台完成图像的合成。这样通过对图5所示的三帧图像进行合成，可以得到合成图像。For example, as shown in Figure 5, the first image on the left is the first image taken by the free gimbal. Since multiple frames were taken, you can click on this area to pop up a series of relatively clear images saved, and select the clearest image based on user input. image. The second from the left and the third from the left are the extended images obtained by rotating the fixed gimbal and the mobile phone, which can be freely selected by the user to supplement more scenes than the initial shooting scene. After the user selects an image to be synthesized, the image is synthesized in the background. In this way, a composite image can be obtained by synthesizing the three frames of images shown in FIG. 5 .
之后，若用户继续拍摄图像，则返回执行步骤202，否则退出相机结束。After that, if the user continues to capture images, return to step 202; otherwise, exit the camera and end.
这样，本申请实例通过自由云台和固定云台，既锁定了起始的拍摄位置，又可以补充手机开始旋转后的图像部分，最后通过图像的合成，完成多帧场景下的拍摄。In this way, the example of the present application uses the free gimbal and the fixed gimbal to not only lock the initial shooting position, but also supplement the image part after the mobile phone starts to rotate, and finally complete the shooting in a multi-frame scene through image synthesis.
